Thisinv'ention relates to tslubb'ers or'yarn' cleaners, that is, devices forremoving slulos thlckened portions or'bad places n the yarn,

from the yarn'in spooli'ng or winding-machines, llllQSBfilQVlCCS being lntendedand actingf to" prevent any. thickened portion or "slub; from passing;through an aperture or,

Other objects will appear in. the course of the following description;

My invention is illustrated in the accom 'panyin'g drawings, wherein Figure l is a front elevation of ny. improved yarn cleaner; 7 I

Referring to these drawings, designates a base platehaving upstanding ears 11 apertured at 12 for the'passage of screws, this plate being formed adjacent the ears with :integralbearings 13-having a longitudinally extending screw 14 which is mounted to rotate in these bearings. The screw at one end is provided with ahead 15 and at'the otherend l with am nut 16 whereby the screwmav be held in any adjusted position, the head of the screw being provided with a nick whereby a screw-driver may be used'forturningthe screw. -T hev thread on the screw is relatively line and of very slow pitch.

7 Mounted upon the -base 10 immediately in 1 front of the screw is aplate 17' which projects out at right angles to'the face of the base 10 1 and the 1 1 3 face of this base is formed with y a longitudinally extending yarn receiving groove 18, whose character will be more specificfally stated later as the character of this groove is very important. a p I Spaced from the endsoftheplate 17 are the-porcelain guides 19 and 20. The guide 7 19 is supported slightly below the levelofthe entrance of the groove 18, the guide 20 being higher than the member 17, or leveltherewith Mounted upon the screw 14 is a yarn engag I 10 is a spring 24 having a length equal to ing arm 21 of relativelyhard metal, the inner end of this armbeing screw-threaded for engagement by the screw 14 so that as the screw 14 is turned in one direction or the other, the arm 21 will be caused to travel one direction or the other along the screw and over the plate 17. The arm 21 is capable of being turned down upon the upper face of the plate 17 or turned'to a vertical position entirely away from the plate 17. Preferably the arm is formed of a steel stamping, the inner end of the arm being bent as at 22 to partially embrace the screw 14 and the in-' ner face of thisbent portion. 22 is screw-, threaded so as to constitute a nut." The bent.

portion 22 extendsaround the screw 14 sufficiently so as to hold the arm upon the screw in all positions of the arm. The rear ex tremity of the arm is formed with an angular lug 23'and mounted upon the back of the base the traverse of the arm 21, the upper margin of this spring being engaged beneath the lug 23; This spring thus yieldingly holds the arm 21 down on to the face of the plate 17 but the arm 21 may be turned upward into a vertical position and in this position, the

spring will hold the arm 21raisedL Whenever it is desired to adjust the arm 21 longitudinallyof the plate 17, the screw 14 is turned and'theifis locked by the jam from Figure 3, isso formed that the arm does not bear against that portion of the faceof the plate 17 inward of the groove 18, but

bears against the margin of the plate outward of the groove 18., this margin being very sllghtly raised as shown exaggeratedly' in Figure 3. The groove 18 isof vital impor tance in my constructlon. This groove as will be seen from Figureg5is tapered bothas to width and depth from one end to thefother and constitutes a channel alongwhich the yarn a moves. This groove at its entrance end is large enough to' receive the yarns'of largest diameter, but at its other end, the

grooveis decreased so that it will receive only fluff on the face of the plate 17 from holding yarns of the very smallest diameter. 4

*In the use of this device, the arm 21' is turneddown over the face of the plate17" and extends overthe groove 1 8's'o that the under face, of, the arm 21 and thewall of the ness or fineness it may be, runs freely under all circumstances, travelling through this aperture with a minimum degree of friction or wear. .When, however, a slub or thickstopped and the yarn willbreak,thus requir 7 ing as is usual, the-operative to breakout through which the yarn to be cleaned passes and this apertureis: adj ustableto an infinity of diameters by adjustingthefarm .21 along the plate 17 either'toward one end of the plate or towardthe other. c

When the arm 21 is adjusted toward the large'end of the groove 18,,it is adapted for yarns of large diameter. When adjusted at the oppositeend of the plate, it is adapted to 0 clean yarns of the very smallest diameter and obviously: between these two extremities the arm is adjustable to sui't'yarns of every pos-' sible diameter and of every possible character. i i

threading, as it may be called, is quickly and easilyaccomplished after the yarn has been It will be seen that the operation of re-, I

broken 'out and the ends retied, because of the fact that the ,arm 21 is capable of being lifted up, andthere is no necessity of insert- "ingor threading the yarn through an aperture, particularly an extremely fine aperture. The yarn cannot possibly get out offthe groove 18 or become unthreaded.

By the use of this device, the manufac= turer has complete control over the yarn turned out as by adjusting the arm in one direction or the other, the diameter of the thickened portions ofthe-yarn which may be allowed to pass is controlled. The adjustment may be' made, as before stated, while the machine is running and the adjustment is so simplethat any operator can readilyhmakeitf While Ihave illustrated a particular embodiment of my invention which I havefound extremely effective for'the purpose designed,

I do not wish tobe-limited to this embodiment as many changes 'or modifications might be made in the'structur'e of the device'without departing from the principle of the same-as stated in the appendedclaimsfi I L the arm 21 It is to be, understood that touches on both "sides of the groove 18, but that from the inside of the groove to the inside of the member 17, the arm does not quite touch so as to prevent any collection of the arm up. Further by raisingthe margin oftheplate slightly on each side of the groove, it is possible to effectively decrease r "the, depth of the" groove by grinding the face groove constitute practically an aperturef I through which the yarn, of whatever coarse of theplate.
